Description :
Experiments using fungi strains isolated from basaltic boulders allow one to decipher biological weathering. A historical approach using heterochronous moraines provides the opportunity to follow the life of weathering rinds and helps to build a chronology of dominant processes of weathering during the first century of exposure. It appears that exfoliation of weathering rinds, commonly observed on boulders, is the result of a combination of both biogeochemical and physical processes.
